`T all who-'m t may concern v chine, ot' which the'followingisfa specifica- 4 pling 14.`

Be it known that I, ALLEN CLYMER AUS- TIN, a citizen of the United States, and a resident of Syracuse, in the county oi' Onondaga and State of .New York, have invented a certain newand useful` Pressing-Mation.

This invention relates to garment pressing machines and has for its obJect a pare ticularly simple land efficient toggle mechanism for operating the movable pressing element, or head of a machine ofthe type disclosed in my Patent, No. 1,252,988, issued `January 8,1918, upon an application filed October 5, 1915, of which this application .is a division.

In describing this invention, reference -is had to the accompanying drawings in which like vcharacters designate corresponding vparts" in all the views.

y Figure 1 is aside elevationpartly in section, of my garment pressing machine.

Fig. 2 is a planview of parts seen in Fi 1. l f lig. 3 is a detail View, partly in section, of the toggle linksr and contiguous parts.

Fig. 4 is afragmentary view illustrating in planand partly in' section, the frontend of the operating lever.

" `This pressing machine comprises, generally," a frame, pressingl elements usually called bucks,` one of which as .the lower buck is mounted on the frame and the other of which is a pressing head movable toward and from the lower buck, a movable car- 'riage in thel form of a frame lever carrying the pressing head, and operating means for the movable carriagel or frame lever.l

1 designates the vframe which may be of any suitable form, size and' construction, it being here shown as consisting of a table 2, front legs 3, a single rear leg 4, and a `bracket 5 extending upwardly from the way between the' sides of the machine.

rear leg, the rear leg being arranged mid- V 6 designates the lower buck, and 7 the upper buck or'pressing head, the lower buck being mounted upon a bracket 8 resting on lthetable 2L s V9 is the carriage or frame lever support- `ing the vpressir'ig head '7, this lever being double in construction andthe branchesy lthereof having` hubs 1() mounted on a pivot or. shaft 11 located in a bearing 12 at the upper end ofthe bracket 5,1thepressing head bein carried by the front arm of the lever 9. hese bucks are heated bya suitable medium as steam which is conducted v clude an arm 18 connected to the lever 15 at its lower end and a link 19 pivoted at 20 to the upper end of the arm 18 and at 21 to the rear arm 16 of the frame lever 9, one of these links 18, 19 being adjustable in an endwise-directionl and being also slidable endwisely and provided with means for holding 1t from endwise sliding movement, this means being preferably constructed to vyieldingly resist the endwise sliding movement when suflicient pressure is applied to overcome the resistance of the yielding As here shown, the arm or link 18 is rigid with the vlever 15 and the link 19 is endwisely adjustable and also slidable endwisely relativelyto ythe link 18.

In this form of my invention, the link 19 includes two end members 22, 23 and arod 24 connecting the end members. Theend member 22 includes a bearing 25 mounted on the pivot 21 at the rear end of the arm `16 of the frame lever 9, and a threaded socket arranged at an angle to thebearing in which socket the upper end of the rod threads. The end piece 23 is in the form of a shackle pivoted at 20 to the upper end of the link 18 and having a passage in which the lower end of the rod 24 slides, the rod being Vformed with a head 26 which prevents withdrawal of the rod 24 out of the,

.passage of the member 23.

The means for yieldingly holding the rod 24 from endwise sliding movement inthe passage of the member 23 includes a nut 27 threading on the rod toward and from the member 23, and a spring 28 interposed between the nut 27 and the member 23. Al-

though if desired the spring can be omitted and the nut turned directly against thel upper end of'the member 23. The nut 27 lsin the form of a hand wheel which is held 1n its adjusted position by a suitable lock nut 29. Means is provided for limiting the movement of the toggle relatively to the a dead center line of the toggle, that is a straight line passing through the pivots 25, 17. Said means comprises suitable stops 30 and 31 which are here shown as mounted on the endwisely slidable rod 32 pivoted at 33 to the arm 18 and slidable through a passage 34 in the rear leg 4 of the frame, the stops 30 and 31 being arranged to engage the rear leg on the front and rear sides thereof. The stop 30 which limits the movement of the toggle joint 20 toward the dead center line may be arranged to lock the toggle joint 2O in the dead center line or after the joint has passed into and beyond the dead center line.

The operating means also includes a counterbalancing weight 35 having arms or brackets 36 provided with hubs mounted on the pivot 25 on opposite sides of the rear arm 16 of the frame lever 9, these arms extending forwardly and pressing upwardly at 37 on the under side of a web 38 extending between the brackets of the rear end 16 of the frame lever 9.

The pedal lever is provided at its front end with a suitable foot piece 39 adjustable vertically relatively to the pedal lever 15 and to the bed or floor upon which the machine stands, this foot piece being here shown as pivoted at 40 to the front end of the pedal leverl 15 and having a rearwardly extending arm 41 which is adjustably secured to the pedal lever l5 by means of a .fastening member as va bolt 42 extending throu h an opening in th'ep'edal lever y15 and t rough the slot 43 lin-the arm 4l of the foot piece. The pedal lever 15 is usually provided with a series of teeth 44 on the face thereof opposed to the arm 41 of the foot piece 39, and the arm 41 is provided with a single tooth 45 arranged to enter between any two of the teeth 44 so as to firmly hold thel foot piece in its adj usted position after the nut of the fastening member 42 is tightened.

Obviously by reason of the pivotal connection 40 and the pin-and-slot connection vbetween the foot lever 15 and the foot piece 39, the foot piece can be adjusted at anyl height within a certain range.

In operation, the rod 24 of the toggle link 19 can be adjusted to the proper length depending upon the. thickness of the' garment being pressed and the weight of the operator, and the tension of the spring 28 can also be adjusted to the thickness of the garment and to the weight of the operator.

When the pedal lever 15v is depressed the parts move into the position shown in Fig. 1 until the toggle joint 20 comes into or beyond a straight line, the spring yielding to permit the toggle to come into or .pass the straight line, and the stop 30 limiting the movement of the toggle into or beyond a straight line and lockingthe toggle in its operative position. When it is desired to remove the pressure, the toggle joint is broken by pressing upon a lever 46 located near the foot piece 39 and pivoted at 47 to a lug 48 provided on the frame and having a shoulder 49, pressing upwardly on the under side of the lever 15 so that when downward pressure is applied to the lever 46, the pedal' lever is pushed upwardly and the toggle joint 20 moved rearwardly out of the dead center line of the toggle, permitting the spring 50 and the weight 35 tol-aise the pressing head 7.

What I claim is:

1. In a pressing machine, a frame, a movable pressing element, a lever pivoted between its ends between the vframe and carrying the pressing element at its front end, a pair of links pivoted together at contiguous ends, one being pivoted at its other end to the rear arm of said lever and the other being pivoted at its other end to the frame, one of said links including end pieces, and a rod fixed to one piece and slidable in the other, the rod being threaded, a nut threaded on the rod and a spring interposed between the nut and the end piece in which the ypivoted to said lever, and a'weight acting .on said lever and mounted` on the pivot connecting said meansv and the arm-of said lever, substantiallyk as and for the purpose described. f

3. In a pressing machine, a movable pressing element, a lever pivoted between its ends and supporting the movable pressing element on one arm thereof, and mechanism for operating the pressing element'comprising means pivoted tothe other arm of said lever, and a weight mounted on the pivot connecting said means and the arm of said lever, the weight having a forwardly extending arm pressing upwardly against the supporting lever in front of the pivot thereof, utlstantially as and for the purpose speci- In testimony whereof, I have hereunto of Ononda 11th day o April, 1916.
